支付宝退款接口BUG： 已经确保了应用配置正确，退款等单号信息正确； AliPayController

出问题代码：

 /**
     * 退款
     */
    @RequestMapping(value = "/tradeRefund")
    @ResponseBody
    public String tradeRefund() {

        try {
            AlipayTradeRefundModel model = new AlipayTradeRefundModel();
            model.setOutTradeNo("042518161915246");//商户订单号       
            model.setTradeNo("2018042521001004610572946934");//支付宝订单号
            model.setRefundAmount("0.01");
            model.setRefundReason("正常退款");

            AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do",AliPayApiConfigKit.getAliPayApiConfig().getAppId(),
                    AliPayApiConfigKit.getAliPayApiConfig().getPrivateKey(),"json","GBK",
                    AliPayApiConfigKit.getAliPayApiConfig().getAlipayPublicKey(),"RSA2");
            AlipayTradeRefundRequest request = new AlipayTradeRefundRequest();
            request.setBizModel(model);
            AlipayTradeRefundResponse response = alipayClient.execute(request);
            //return response.getBody();
            return AliPayApi.tradeRefund(model);
        } catch (AlipayApiException e) {
            e.printStackTrace();
        }
        return null;
    }

出问题报参数 appid无效！后面我改成下面的方式，就退款成功了，非常疑惑，不止为何，我也相信看了楼主的封装代码，AliPayApi.tradeRefund(model);里面的代码没有看出问题来。

{
alipay_trade_refund_response: {
code: "40002",
msg: "Invalid Arguments",
sub_code: "isv.invalid-app-id",
sub_msg: "无效的AppID参数"
}
}

正常代码：

    /**
     * 退款
     */
    @RequestMapping(value = "/tradeRefund")
    @ResponseBody
    public String tradeRefund() {
        try {
            AlipayTradeRefundModel model = new AlipayTradeRefundModel();
            model.setOutTradeNo("042518161915246");//商户订单号       
            model.setTradeNo("2018042521001004610572946934");//支付宝订单号
            model.setRefundAmount("0.01");
            model.setRefundReason("正常退款");

            AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do",AliPayApiConfigKit.getAliPayApiConfig().getAppId(),
                    AliPayApiConfigKit.getAliPayApiConfig().getPrivateKey(),"json","GBK",
                    AliPayApiConfigKit.getAliPayApiConfig().getAlipayPublicKey(),"RSA2");
            AlipayTradeRefundRequest request = new AlipayTradeRefundRequest();
            request.setBizModel(model);
            AlipayTradeRefundResponse response = alipayClient.execute(request);
            return response.getBody();
                    //AliPayApi.tradeRefund(model);
        } catch (AlipayApiException e) {
            e.printStackTrace();
        }
        return null;
    }

}

请楼主看下，这是为何？appid已经配置成功了，拦截器拦截的时候把appid也通过配置类传入，但是还是发生了上面的参数无效 appid.
